Product details
Overview
P6SMB200AHM3_B/H from Vishay General Semiconductor is a unidirectional surface-mount Transient Voltage Suppressor (TVS) diode in SMB (DO-214AA) package, rated for 200 V standoff voltage (VWM), 210 V minimum breakdown voltage (VBR), and 274 V maximum clamping voltage (VC) at 2.2 A peak pulse current (IPPM), designed to protect power rails and signal lines in automotive and industrial systems against ESD and lightning-induced transients.
For engineers reviewing the P6SMB200AHM3_B/H datasheet, P6SMB200AHM3_B/H pinout, P6SMB200AHM3_B/H application, or P6SMB200AHM3_B/H equivalent, this device delivers AEC-Q101 qualification, 600 W peak pulse power (10/1000 μs), low thermal resistance (RθJL = 20 °C/W), and halogen-free RoHS compliance - critical for automotive-grade surge protection design validation.
Technical Context
The P6SMB200AHM3_B/H operates as a unidirectional avalanche diode with glass-passivated junction, enabling sub-nanosecond response to transient overvoltages. Its clamping behavior is defined by a 274 V VC at 2.2 A IPPM under 10/1000 μs waveform, with 0.108 %/°C temperature coefficient of VBR ensuring stable breakdown across -65 °C to +150 °C junction range.
Designed for automated SMT placement on PCBs with 0.2" × 0.2" copper pads per terminal, it meets MSL Level 1 (peak reflow 260 °C) and JESD201 Class 2 whisker resistance. The cathode band marking identifies polarity, and its SMB package supports 5.0 W steady-state power dissipation at TA = 50 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 171 V - Maximum continuous reverse operating voltage before conduction begins; defines safe working margin below clamping threshold. |
| VBR (Breakdown Voltage) | 190–210 V at IT = 1 mA - Confirmed avalanche initiation range; ensures predictable turn-on during transients. |
| VC (Clamping Voltage) | 274 V at IPPM = 2.2 A - Peak voltage seen by protected circuit during 10/1000 μs surge; determines downstream component stress. |
| PPPM (Peak Pulse Power) | 600 W - Surge energy handling capacity under standardized 10/1000 μs waveform; validates robustness against IEC 61000-4-5 threats. |
| TJ max. | +150 °C - Maximum junction temperature rating; enables operation in under-hood automotive environments and high-ambient industrial settings. |
| RθJL | 20 °C/W - Low junction-to-lead thermal resistance; supports efficient heat transfer to PCB copper, critical for repetitive surge reliability. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronic modules per stress test requirements including HTOL, TCT, and ESD; designated by HM3_B suffix. |
Pinout & Package
Package: SMB (DO-214AA), surface-mount, low-profile case with matte tin-plated leads solderable per J-STD-002 and JESD22-B102. Cathode identified by black band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMAJ200A-E3/5B | Same VWM (171 V), but lower PPPM (400 W); SMA package (DO-214AC), RθJA = 110 °C/W vs. 100 °C/W | Not AEC-Q101 qualified; suited for commercial-grade consumer/industrial designs with lower surge severity | Select if cost-sensitive and AEC-Q101 not required; verify thermal margin due to higher RθJA. |

FAQ
What is the clamping voltage of P6SMB200AHM3_B/H at its rated peak pulse current?
The P6SMB200AHM3_B/H has a maximum clamping voltage (VC) of 274 V at 2.2 A peak pulse current (IPPM), measured under the standardized 10/1000 μs waveform. This value defines the upper voltage limit imposed on protected circuits during surge events and is confirmed in the Vishay datasheet revision 09-Jan-2024, page 2. The P6SMB200AHM3_B/H maintains this clamping performance across its specified operating temperature range.
Is P6SMB200AHM3_B/H qualified for automotive applications?
Yes, P6SMB200AHM3_B/H is AEC-Q101 qualified, as indicated by the "HM3_B" suffix per Vishay's ordering information (page 3). It undergoes stress testing for high-temperature operating life, temperature cycling, and ESD robustness required for automotive electronics. The P6SMB200AHM3_B/H is explicitly recommended for engine control, body electronics, and ADAS modules where reliability under thermal and electrical stress is mandatory.
What package type does P6SMB200AHM3_B/H use, and what are its key mechanical features?
P6SMB200AHM3_B/H uses the SMB (DO-214AA) surface-mount package, measuring 4.57 mm × 3.94 mm × 2.20 mm. Key features include matte tin-plated leads compliant with J-STD-002, UL 94 V-0 flammability-rated molding compound, and MSL Level 1 rating for lead-free reflow. The cathode is marked with a black band, and the package supports 0.2" × 0.2" copper pad layout per terminal for optimal thermal dissipation - all verified in the Vishay P6SMB Series datasheet, page 5.
How does the thermal resistance of P6SMB200AHM3_B/H affect its surge handling capability?
P6SMB200AHM3_B/H has a typical junction-to-lead thermal resistance (RθJL) of 20 °C/W, enabling efficient heat transfer from the silicon die to the PCB copper pads. This low RθJL sustains repeated 600 W surge events without thermal runaway, especially when mounted on 0.2" × 0.2" copper areas. Its RθJA of 100 °C/W also supports reliable operation at TA = 50 °C with 5.0 W steady-state dissipation - critical for P6SMB200AHM3_B/H deployment in enclosed automotive or industrial enclosures.
What is the reverse leakage current specification for P6SMB200AHM3_B/H at its maximum standoff voltage?
At its maximum stand-off voltage (VWM) of 171 V and TA = 25 °C, the P6SMB200AHM3_B/H exhibits a maximum reverse leakage current (ID) of 1.0 μA, as specified in the Vishay datasheet (page 2, Electrical Characteristics table). This ultra-low leakage preserves system efficiency in always-on automotive modules and ensures minimal power loss in high-impedance sensor interfaces - a key design advantage of the P6SMB200AHM3_B/H over higher-leakage alternatives.
